*****
Tom woke up before me on a Saturday morning and began a marital assault on my naked body underneath the sheets of our bed. I awoke to the feel of his strong hands roaming all over my torso and breasts, quite enjoying the way he fondled my hips and reached his fingertips just over the curve of my ass and dug them into my soft flesh. I moaned appreciatively and genuinely looked forward to the sex we were about to have.
As he roughly entered me, just as I liked it, I found myself imagining my son fucking me. This was not the first time such thoughts had entered my mind, and also not the first time while his father was having his way with me. I felt guilt begin to cloud out my reverie and though I climaxed still, with Tom's modest cock impossibly hard as it twitched and erupted inside of my cunt, I knew that it should have been more. It should have been a private moment between husband and wife and no one else. What had I allowed to happen?
As I enjoyed my morning coffee at the kitchen table some minutes later, I kept replaying the moment in my mind. I was still quite wet from the previous activity with Tom and was dripping his cum into my panties. I slid two fingers down into my shorts and over my panties to rub against my mound sensually. The slickness was definitely there and I would have to change my clothes before leaving the house today. I closed my eyes momentarily as I enjoyed the sensation, but was soon taking another sip of coffee absently and returning my attention to the morning news on my iPad. The magic was just not quite there at a level that it was when it was Matt's cum leaking out of me.
What mother thinks of these things? I chastised myself.
Breanna came downstairs just then and barely noticed me as she walked into the kitchen toward the coffee pot. I watched her pour herself a cup and mix some milk into it, admiring how youthful she still was. I had grown to notice her womanly curves and overall beauty even more now that I had seen her use her physical assets in action. How many times was it by now? She had taken at least a dozen of her brother's loads inside her tight pussy by this point, some in her ass too, and at least a few down her throat or on her face. I was too old to understand the appeal of that one, at least from the woman's point of view, but Breanna seemed to genuinely enjoy it happening to her. It was fun to watch, I had to admit. Perverted, but fun.
"Good morning," I finally said to her.
She turned to smile at me with a tired look in her eyes. "Morning. How was the sex?"
I blushed, but didn't deny anything. "Did you even hear your father leave this morning? Maybe he's right around the corner and listening to you."
She shook her head. "I know the rules. Two minutes. He's been gone for longer than that."
She was repeating the rule I had made my children swear to obey if they were to engage in incestuous fornication in this house. Only when their father wasn't around, and never right after he left. There was always the chance he could forget his phone or something and return home for it. Heaven only knows what he would do if he walked into the living room to find his children having sex. Or worse, me having sex with them.
I took a sip of my coffee but kept my eyes on her. "The sex was fine, thank you. How was your sex?"
She raised an eyebrow at me. "Nice try. I'm a good girl. I don't break the rules."
"Oh?" I kept up the pretense that I was skeptical, but this was only a test. I trusted that she wouldn't lie to me.
She matched my skeptical look and sipped her own coffee confidently. "Never. It's too much fun to make Matt wait. We don't even sext or talk about it in any electronic manner. Only verbally, and only in private."
I smiled. "You are a good girl. I never doubted you. Just testing like a mother should."
She giggled and came to sit next to me at the table. She had her phone out for a moment but seemed distracted.
"Is it hard to have sex with Dad now?" The question came out abruptly.
I swallowed but hid my shock. "Why would you think that?"
Breanna shrugged. "I sometimes picture fucking other guys now, besides Matt, and it just doesn't have the same appeal that it used to. That 'kink' isn't there anymore, running around and being bad with boys. I'm being way badder at home with Matt than I could ever be with other boys."
"And just how 'bad' we you before you started fucking your brother?" I purposely kept my language salty and frank to keep up with her.
"Oh, there were blowjobs and the like. A couple of fucks here and there when I was super horny and the boy was special. I'm never too horny to think straight though because I have sex whenever I want it, and I'm starting to wonder if that's a bad thing."
"Is it a bad thing that you won't get knocked up or get some STD?" I countered. "How is it bad that you cultivate a loving relationship with your brother by indulging in sex with him that is entirely consensual and safe? It is safe, right?"
Breanna nodded firmly. "Oh, definitely. I never miss a pill. To be honest, I think he likes cumming 'on' me more than 'in' me and I'm just fine with that. If it's inside me it's usually in my ass anyway."
Yes, I knew that they were frequent partakers of anal pleasures. Matt had a big cock but Breanna had a hungry ass. She absolutely loved anal sex.
"Hey, has he been fucking you enough?" She looked actually concerned all of a sudden. "I'm not sapping his energy too much, am I?"
I gestured the thought away with my hand. "He's young. He took on four girls at once, remember?"
She laughed. "Yeah and it almost killed him. He didn't even cum the next time we fucked."
I sighed as I remembered that trip not more than a week ago. "Your aunt really needed that. Kristie too. What a treat that the whole thing worked out."
"Matt says Kristie has been sending him naughty texts since then. He keeps her number out of his address book though so no one would know who it was."
I was honestly impressed. I would have thought that she might have simply...moved on, I guess. "Pics?"
Breanna nodded. "Really, really dirty ones too. We usually look at them together and then fuck each others' brains out."
"That makes me happy," I replied, sipping my coffee again as if this was a very wholesome thing for a mother to hear about her children and their cousin. "You're letting him jerk off once in a while, right?"
She looked confused, actually. "...Why? Isn't sex with me better?"
